cinder volume-type misunderstanding?

Hi, I set up an openstack 2023.2 bundle and a 3HA juju controllers. I have a ceph-cinder volume-type named SAS (sorry I didn’t use cinder, but it was for migrating an older ceph cluster). I’d like to deploy charms by juju but every one is not deployed on my cinder/ceph volume. My conf:

openstack volume type: Ubuntu Pastebin

juju storage-pools: Ubuntu Pastebin

juju model-config: Ubuntu Pastebin

juju storage is empty . Every deployed VM has its root disk on a nova unit instead of SAS cinder storage-pool: any idea?
